Participants

Reaction Steps

The olefin of Example 5 (2.6 g, 8.7 mmol) in EtOAc (50 mL) at room temperature is stirred under a hydrogen atmosphere (1 atm) in the presence of 10% Pd/C (500 mg) overnight. The reaction mixture is then purged with argon, followed by filtration through a Celite pad. Concentration of the filtrate followed by flash chromatography (10% EtOAc in hexane) gave the title ester (2.4 g, 92%) as a crystalline solid.
